Introduction: Gutta-percha on temperature above 49 degrees becomes plastic and intensively fills the canal system.
Objective: The aim of this study was to analyze canal obturation with modified conventional gutta-percha technique thermo plasticized with Nd:Yag laser.
Materials and methods: Thirty single-rooted human teeth were used in this experimental research. Endodontic treatment was performed of all teeth and according of gutta-percha were categorized in 2 groups of 15 teeth. Root canal filling was performed with AH plus sealer and modified single cone gutta-percha technique in the first control group. In the second group after applying of AH plus and modified single cone gutta-percha technique finally with Nd:Yag laser beam were thermo plasticized.
In successive procedure the crowns were cut with turbine and diamond burs. Teeth roots were divided on three cross-cut segments with thickness of 2mm, one in orifice level, one in middle and one in apical third with turbine and specific burs.
Quantitative and qualitative analysis and evaluation of canal obturation and its marginal adaptability were performed with SEM by two irrespective researchers.
Results: Evaluations made with SEM showed that gutta-percha technique thermo plasticized with Nd:Yag laser can be performed and it is possible.
Conclusions: Obturation with gutta-percha technique thermo plasticized using Nd:YAG laser beam results with better root canal obturation when is compared to conventional methods. Using of lasers also can provide adequate cleaning and shaping, which contribute to the success of root canal treatment.
